HERMAN BARDITZKY, OF FLORENCE, ALABAMA.

COTTON-SEED-DELINTING MACHINE.

' SPECIFICATION forming part of Letters Patent No. 662,337, dated November 20, 1900.

Application filed April 26, 1900. Serial No. 14,477. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN BARDITZKY, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented certain new and useful Improvements in Cotton-Seed-Delinting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of machines employed for removing the lintor fiber from cotton-seed after it leaves the gin, and well known as delinting-machines.

The object of the invention is to generally make the construction of such machines with a view to great-er capacity, economical construction, simplicity, and rapidity of opera tion.

Withthis object in view the invention consists in the improved construction, arrangement, and combination of the parts of a machine of this class, which will be hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view, parts being shown in elevation. Fig. 2 is a transverse vertical sectional view. Fig. 3 is a detail perspective view illustrating the teethplate securing and adjusting mechanism.

Wherever the same parts occur in the different figures they are indicated by the same reference-numerals.

Referring to the drawings by numerals, 1 indicates the main body or casing of the machine, which may be made of any suitable material and is intended to inclose the principal parts of the machine. Surmounted upon the main casing is a seedbox 2, having vertical side and end walls, the front side walls 3 being provided at their lower ends with a series of horizontally-projecting steel teeth 4, said teeth being either formed integral with the metal plate forming this wall or they may be made separate and secured thereto in any suitable manner. Journaled in suitable bearings 4 in the end walls of the seedboX is a horizontal shaft 5, which is provided with solid radial blades 6, preferably four in numher, and located in pairs at right angles to each other, said blades extending the greater portion of the length of the shaft, the remainder of the shaft being provided with radiallyarranged and stagger-ed stirring-teeth '7. The seedbox is covered, except for that portion in which the stirrer-teeth are located, above which latter portion is mounted a hopper 8.

In the main frame 1 beneath the open bottom of the seedbox is journaled the horizontal main shaft 9, upon which is mounted an abrading-roller 10, preferably covered with card-clothing, which roller is so located. that its periphery during its rotation will pass in close proximity to the points of the teeth 5 and also in close proximity with the lower end of the rear wall of the seedbox. The front plate 3 of the seedbox which carries the teeth 4, as above stated, is supported by means of a right-angled bracket 11, secured to the plate by a bolt 12 and to a horizontal flange 13, projecting inwardly from the top of the main casing by a bolt 14, one of the openings for each of the bolts being enlarged,so as to permit of the horizontal or vertical adjustment of the plate 3 and teeth 4 in order to secure the teeth in proper position relative to the periphery of the abrading-roller.

Within the main casing, in substantially the same horizontal plane as the main shaft 9, is journaled a shaft 15, on which are mounted fan-blades 16.

Below the roller 10, within the casing, is a second seedbox 17, the front plate 18 of which is provided with teeth 19, similar in form and position to the teeth 4 of the plate 3, and

within this lower seedbox 17 is journaled a horizontal shaft 20, provided with solid radial blades 21. Immediately below the open bottom of the seedbox 17 and within the main casing is journaled a horizontal shaft 2, upon which is mounted an abrading-roller 23, preferably of the same form and con struction. as the roller 10, said roller being so located that in its rotation its periphery will pass in close proximity to the ends of the teeth 19 and the lower end of the rear wall 20 of the seedbox 17. The front wall 18 of the seedbox 17 is adjustably mounted on a horizontal flange 24 by means of a bracket 25 and bolts in the same manner as the front plate 30f the upper seedbox is secured to the flange v13, whereby the plate 18 and teeth 19 are adjustable vertically and horizontally secure the teeth in proper position relative to the periphery of the roller 23. In the main casingin front of the roller 23 is journaled a shaft 26, upon which are mounted fan-blades 27.

The lower end of the casing 1 terminates in a horizontal spout or duct 23, open on its under side to receive an endless belt 29, mounted upon and driven by suitable rollers mounted on shafts at each end of the belt, one of which is shown at 30, the outer end of the belt being broken away and the outer supporting-roller omitted. The casing is supported upon suitable legs, as at 31 32.

The seedbox 2 is provided with an opening in its end wall at the left, as shown in Fig. 1, which may be closed wholly or partially by means of a sliding door 33, operated by a han dle 34, to permit of the passage of seed out of the seedbox into a spout 35, by means of which the seed are conducted into the lower seedbox 17. The lower seed-box is provided with a sliding door 36 at its opposite end, through which the seed is discharged into a spout 37, which may be constructed of any suitable form to properly conduct the seed to any receptacle prepared to receive it.

On the shaft 9 may be mounted a suitable pulley 38, from which a crossed belt 39, as indicated in dotted lines in Fig. 2, is passed to a small pulley on the shaft 15, whereby the fan-blades 16 are rotated in the direction indicated by the arrow at a higher speed thanthe blades 6 and teeth 7 are rotated at a shaft 26, with its fan-blades 27, are rotated from the shaft 22, the shaft 20 slower and the shaft 26 faster than the shaft 22, by means of substantially the same arrangement of belts and pulleys as is used to rotate the shafts 5 and 15' from the shaft 9, as heretofore described, the direction of rotation of each shaft being indicated in Fig. 2 by means of arrows.

In the operation of the invention cottonseed placed in the hopper 8 drops into the seedbox in that end in which the teeth 7' will rotate, said teeth serving to stir and agitate the mass of seed. The seed is then carried around by the abrading-roller into contact with the teeth 4, which are sufficiently near together to prevent the seed dropping between them,and the abrading-roller operating upon the seed held up by the teeth will clean the lint therefrom, the seed being kept continually in motion and rolled about upon the teeth 4 until substantially free from lint. The pressure of the seed in the hopper upon that below and in the seedbox 2 will cause the seed to gradually pass along to the left over the teeth 4 until the opening at the opposite end of the rolleris reached. The door 33 being opened to an extent determined by experience, the seed will pass through it and through the spout 35 into the lower seedbox 17, being stirred and pressed downward during its passage through the upper seedbox by the blades 6. In the lower seedbox the seed will be pressed downward and toward the plate 18 by the blades 21, and in addition will be carried by the roller in the same direction, causing the seed in the lower box to lodge on the teeth 19 of the plate 18 to undergo a repetition of the treatment received in the upper seedbox, the seed gradually working its way to the opposite end of the lower seedbox and roller 23 and finally passing out through the opening covered by the sliding door 36 into the spout 37, through which, as before stated, it is delivered in a perfectly clean condition to any suitable receptacle. The cotton stripped from the seed by the abrading-rollers will be carried downward, as indicated by the arrows in Fig. 2, and forced along by the currents of air caused by the rotation of the fan-blades 16 and 27 until it passes upon the endless belt 28 and by it is delivered through the horizontal belt into any suitable receptacle placed to receive it.

, By means of the construction herein described the lint is quickly and cleanly removed from the seed, the seed delivered from one end of the machine in a cleaned and polished condition, and the removed lint delivered at the rear of the machine, the whole operation being rapid and the machinery being simple and economical in construction.

While the specific construction of the various parts has been particularly described it will be obvious to those skilled in the art that changes and variations might be made therein without departing from the spirit and scope of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
